HAND-MOTOR FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 409,581, dated August 20, 1889.

Application filed May 27, 1889. Serial No. 312,296. (No model.)

To aZZ whom it may concern:

Be it known that I, AMAZIAH E. IIARRELL, a citizen of the United States of America, re siding at lVabash, in the county of Wabash and State of Indiana, have invented certain new and useful Improvements in Manual Motors to be Attached to Four-\Vheeled Vehicles, of which the following is a specification, reference being had therein to the accompanying drawings, in which Figure 1 is a perspective view showing the motor attached to a vehicle; Fig. 2, a detail View of brace G and clip H; Fig. 3, a detail View of connecting-rod N and clamp 0; Fig. 4, a detail view of sprocket-wheel I.

Similarletters refer to similar parts throughout the several views.

My invention relates to manual motors or vehicles propelled by manual power; and the object of my invention is a motor which can be attached to any light founwheeled vehiclesuch as a buggy or road-wagon -without altering the construction of such vehicle, said motor being so constructed as to be easily attached to or removed from the vehicle in a few moments; and my invention consists in the improved construction and combination of parts, as hereinafter fully described and claimed.

The crank handle A revolves in bearings in the braces l5 l3, and on its ends outside of the braces are loosely set the sprocket-wheels O 0, each of which has upon its innerface a crown-ratchet I). Into the crankshaft are setpawls (1d, which engage with the ratchets D I) and communicate motion to the sprocket-wheels, the latter being forced againstthe pawls by spiral. springs c c, which are held in place on the shaft by collars or butting-rings O 0. Each of the frontbraces B 13' has at its upper end a bearing for the crank-shaft, and its lower end is pivoted to a screw-clamp E, designed to inclose the upper edge of the side of the vehicle, the thumbscrew 6 securing it in position, as shown in Fig; 1. Each of the rear braces 13 B has at its upper end a bearing for the crank-shaft and in its lower end slots ff, through which pass the adjusting-screws F F, engagingin the bar or brace G, which is pivoted upon a clip II, as shown in Fig. 2, adapted to be attached to the rear axle of the vehicle. By means of the adjusting-screws and slots the braces may be adj ustcd so as to loosen or tighten the sprocketohain. The main sprocket-wheels I I, which are of the shape shown in Fig. I, are mounted upon the inner ends of the hubs of the drivin g-wheels of the vehicle, an d secured in place by bolts passing through the collars it into the hubs. Sprocket-chains J J connect the sprocket-wheels C G with the wheels I I.

The guiding rods or levers K K are pivoted at their fulcrums 7c 70 to screw-clamps LL, adapted to be attached to the sides of the vehicle and held in place by thumb-screws M M, as shown in Fig. 1. The outer ends of the guiding-levers K K are pivoted to the connecting-rods N N, which are bent down toward the front axle and pivoted at their ends an to slips or screw-clamps O O, as shown in Fig. 3, to be attached to the front axle of the vehicle. Y

\Vhat I claim, and desire to secure by Letters Patent, is

1. The combination of crank-handle A, crown-ratcheted sprocket-wheels C, pawls (Z, spiral springs c, braces 3' I3 G, adjustingscrcws F, screw-clamps E, clips H, sprocket wheels I, sprocket-chains J, steering-levers K, screw-clamps L, connectin g-rods N, and screwclamps O, substantially as and for the purposes specified.

2. The combination, with the crank-handle A, pawls d, crown-ratcheted sprocketwheels C, sprocket-chains J, and sprocket-wheels I, of the braces B, pivoted to screw-clamps F., braces B, and braces G, pivoted to clips II, as and for the purposes specified. v

3. The combination of steering-levers K, screw-clamps L, connecting-rods N, and screw: clamps O, as and for the purposes specified.

4. The combination of crankhandle A, pawls d, erown-ratcheted sprocket-wheels O, spiral springs c, sprocket-wheels I, and sprocl et-chains .I, as and for the purposes specified.

In testimony whereof I affix my signature in presence of two witnesses.

AMAZIAII E. HARRELL.
